Patent number: 7865195Abstract: Location positioning setting information is read from a setting storage section when the user depressed a power key. The location positioning setting information comprises setting information, such as the maximum duration time of the location positioning operation and the operation timing when a power-off event has been generated. A control section turns off the power of a display section, a speaker, a microphone, etc., excluding a communication function for transmitting location positioning and positioning results. In this state, a location positioning section acquires the positional information of the mobile communication terminal. Then, a wireless communication section transmits the location positioning information of the positioned mobile communication terminal to a predetermined monitoring server which manages the positional information of the mobile communication terminal.Type: GrantFiled: February 22, 2006Date of Patent: January 4, 2011Assignee: Casio Hitachi Mobile Communications Co., Ltd.Inventors: Masaru Uemura, Takashi Iida, Shinji Ueno, Hidenori Sakaniwa, Shigeyuki Sudo, Norikazau Takahashi, Yoshiaki Umehara

Patent number: 7318467Abstract: A method of manufacturing the caliper body of a vehicular disc brake by the gravity casting method. The caliper body is used for the vehicular disc brake wherein a pair of frictional pads are disposed opposite to each other with a disc rotor held therebetween. The caliper body has a cylinder disposed on one side of the disc rotor, a reaction pawl disposed on the other side of disc rotor, and a bridge for coupling the cylinder and the reaction pawl on the outer peripheral side of the disc rotor. A sprue is provided in the bottom portion of the cylinder, and the caliper body is cast by a cavity with the side of molding the bottom portion of the cylinder disposed in the upper part of and in the vertical direction of the cavity and with the side of molding the reaction pawl disposed in the lower part of and in the vertical direction thereof.Type: GrantFiled: May 15, 2007Date of Patent: January 15, 2008Assignee: Nissin Kogyo Co., Ltd.Inventors: Yoshiaki Umehara, Syoji Kaiume, Takenori Tsuchiya

Publication number: 20040198387Abstract: A position detection system and a portable terminal are disclosed. The portable terminal carries out communication with a server in the first position detection session and thereby acquires the GPS assist information and the base station position information from the server. Using the GPS assist information thus acquired, the portable terminal transmits the GPS signal received from a GPS satellite to the server, and receives the position information of the portable terminal calculated by the server. In the second and subsequent sessions of position detection, the portable terminal neither establishes communication with the server nor receives the GPS signal, but makes calculations for position detection on its own using the result of measuring the radio wave propagation time from nearby base stations, the position information of the portable terminal obtained in the preceding session and the base station position information.Type: ApplicationFiled: January 9, 2003Publication date: October 7, 2004Inventors: Naoki Tsuji, Yoshiaki Umehara, Fumiharu Nakahara, Yoshitaka Imakado
